Xorg configuration fails on G4 Powermac

[Super Biscuit]

My apologies but I do need help from both lists here and the freebsd ppc mailing lists for these problems.

How do I set the output to include two screens- one for each graphics card?

What was the last supported version of Xorg to allow dual graphics cards?

Is it possible to use Xnest or Xephyr with SSH to allow remote logins on a dedicated xclient & xserver?

OF needs to init both cards for them to be usable by X.  For now
you'll probably only have luck with whichever card OF initialized.
